There have been many days when I haven't felt like riding, but there has never been a day when I was sorry I rode.
Maybe they are slow or riding a cruiser?

Seattle fits the bills pretty well.
Light rail, train, ferry, bus can get you to the countryside quick. Mt Ranier is only 70 miles away, you can take a bus even closer. You can be in the foothills of the cascades in 40 miles or less. The ferry system allows you to go to MANY points beyond the city quickly. Amtrak can get you to points even farther.
Yeah, I love it here...
What really helps me is that we decided, even when we had 2 cars, that it would be nice to be centrally located, not too far from a grocery store, restaurants, etc. Although it seemed a fairly minor point at the time, it has proved pretty useful lately.
